IM PROVEM ENT IN PLOWS.

Specificution forming part 01 Letters Patent No. L527, dated March 31, 1840.

T0 ail 107mm may concem:

Be it known that; I, WILLIAM BRYAN1, of 111e connty ofDavidson and State ofTennessee, have invented a new and useful Improvement in Plows; andI hereby declare that the foilowing; is a full and exact description.

The nature of my invention oonsists in fixing bthilld the shnre or cntting part of the plow a colte1, so as to run deeperand Ioosen thegronnd deeper thon it is cnt'by the share.

T0 ennble others skiiled to make and use my invention, I proceed to describe its construction and operation.

I constmct the mold-hoard A ofcnst-iron and in the connnon form,to the iower part of which I atlach by screws Lhe :snare or cutting part; B, made in the common manner of wronght-iron, with a steel edge. The upper part of the 1n0ldboard has a shank, which passes through the beam 0, and is fastened to in by a key-bolt.

About twelve inches behind the mold-board I place the colter D in the beam. It can be fixed higher or lower, as desired, and is fastened by a key-wedge. 113 is made as colters generally are, and placed a few inohes lower than the share, with the point projecting 21 little forward.

lhe handles E E are attached to the beam by a sorew-bolt, and theirlower end, being fustened to the mold-board,serves as a brace toit. When the plow is in use the share and moldboard out and remove the earth as in common plowing, and the colter, passing in the furrow, loosens the earth lower than the share runs.

What I claim as my invention, and desire to secure by Letters Patent, is-

The fixing in the plow a colter behind the share or cutting part,which colter steadies the plow and loosens the enrth lower than the show cuts.
